1st brew airlock problem

[Cnoon]

This is my first attempt at brewing. I had the blowoff tube on and it was bubbling every couple seconds into the bowl of water and sanitizer. I switched to the airlock 3 days later and have not seen any bubbles since. I can see some tiny bubbles in the airlock but no movement.

Do I have a problem?

Probably not. It's quite possible for fermentation to be almost complete after 3 days but it's more probable that it's just slowed down which is normal. Now is the time to use your hydrometer. There are far too many variables to gauge it by guesswork or the bubbling in the airlock. The only way you can tell is by measurement. Keep measuring until it stops going down for at least 4 days. This can sometimes take a while. Your hydrometer is your friend.

Are you fermenting in a bucket?  The CO2 may be escaping around the rim now that CO2 pressure is less.
